multi-core Fiber Unit to the lower hole (Receiver side).
(1) Open the cover.
(2) Raise the lock lever.(Release)
(3) Insert the Fiber Unit in the fiber unit hole to the
bottom.
(4) Return the lock lever to the original position and fix
the Fiber Unit.(Lock)

Warning Indications
WARNING
Do not use the product with voltage in excess of the rated voltage.
Excess voltage may result in malfunction or fire.
Never use the product with an AC power supply. Otherwise,
explosion may result.
PRECAUTIONS FOR SAFE USE
PRECAUTIONS FOR CORRECT USE
Checking the Package Content
• Amplifier Unit: 1 • Instruction Sheet (this sheet): 1 (Japanese, English, Chinese and Korean
)
The following precautions must be observed to ensure safe operation of the product. Doing so may cause
damage or fire.
· Do not install the product in the following locations.
(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations subject to vibration or mechanical shocks exceeding the rated values
(5) Locations subject to exposure to water, oil, chemicals
(6) Locations subject to steam
(7) Locations subjected to strong magnetic field or electric field
· Do not use the product in environments subject to flammable or explosive gases.
· Do not use the product in any atmosphere or environment that exceeds the ratings.
· To secure the safety of operation and maintenance, do not install the product close to high-voltage
devices and power devices.
· High-Voltage lines and power lines must be wired separately from this product. Wiring them together or
placing them in the same duct may cause induction, resulting in malfunction or damage.
· Do not apply any load exceeding the ratings. Otherwise damage or fire may result.
· Do not short the load. Otherwise damage or fire may result.
· Connect the load correctly.
· Do not miswire such as the polarity of the power supply.
· Do not use the product if the case is damaged.
· Burn injury may occur. The product surface temperature rises depending on application conditions, such as
the ambient temperature and the power supply voltage. Attention must be paid during operation or cleaning.
· When setting the sensor, be sure to check safety such as by stopping the equipment.
· Be sure to turn off the power supply before connecting or disconnecting wires.
· Do not attempt to disassemble, repair, or modify the product in any way.
· When disposing of the product, treat it as industrial waste.
· Do not use the Sensor in water, rainfall, or outdoors.
· Use the product in the IP54 enclosure.
· UL Standard Certification
Only the sensors with Enhanced UL Certification Mark are certified by UL. They are intended to be
supplied by a "Class 2 circuit". When used in United States and Canada, Please use the same Class 2
source for input and output.The overcurrent protection current rating is 2A max. They were evaluated as
Open type and shall be installed within a enclosure.
· Be sure to mount the unit to the DIN track until it clicks.
· When using a connector type product, place a protective label (provided with the E3X-CN series) on the
power supply connecting terminals that are not used, to prevent electric shock or short circuit.
· The length for the cable extension must be 30 m or less (or less than 10 m for S-mark certified models).Be sure to use a
cable of at least 0.3 mm
2
for extension.The power voltage must be 24 to 30 V when connecting amplifier units with
extension cable and wire-saving connector.
· Do not apply the forces on the cord exceeding the following limits:
Pull: 40N; torque: 0.1N·m; pressure: 20N; bending: 29.4N
· Do not apply excessive force such as tension, compression or torsion to the amplifier unit with the fiber unit fixed to
the amplifier unit.
· Always keep the protective cover in place when using the product. Not doing so may cause malfunction.
· It may take time until the received light intensity and measured value become stable immediately after the power is
turned on depending on use environment.
· The product is ready to operate 200 ms after the power supply is turned ON.
· The Mobile Console E3X-MC11, E3X-MC11-SV2 and E3X-MC11-S cannot be connected.
· The mutual interference prevention function does not work when in combination with E3C/E2C/E3X.
· If the unit receives excessive sensor light, the mutual interference prevention function may not work properly, resulting
in malfunction of the unit. In such case, increase the threshold.
· The Communication Unit E3X-DRT21-S, E3X-CRT, E3X-ECT and E3NW cannot be connected.
· If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or smoke, immediately stop
using the product, turn off the power, and consult your dealer.
· Do not use thinner, benzine, acetone, and lamp oil for cleaning.
This product is not designed or rated for ensuring safety of persons
either directly or indirectly. Do not use it for such purpose.

Joining Amplifier Units
Up to 30 Amplifier Units can be joined.
Under
environments such as vibration, use an End Plate even
with a single amplifier unit. If mounting the product
without joining the amplifier unit, seal the side optical
communication part with lightproof tape.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
will result in minor or moderate injury, or may result in serious
injury or death.Additionally there may be significant property damage.
DIN track (PFP-
□
N) is sold separately.
Lit up when the smart tuning function is effective. Put out
when the detection function is changed or the settings are
initialized.
(1)
Mount the Amplifier Units one at a time onto the DIN track.
(2)
When using a wire-saving connector, mount the master
connector to A and slave connector to B.
(3)
Slide the Amplifier Unit until the Amplifier Unit is closely
attached.(Arrow 3) (For the wire-saving connector type, be
sure that a master connector and a slave connector, or a slave
connector and a slave connector are connected.)
(4)
Use End Plates (PFP-M: separately sold) at the both ends
of the grouped Amplifier Units to prevent them from
separating due to vibration or other cause.(Arrow 4)
(5)
Tighten the screw on the End Plates using a driver.(Arrow 5)
(1) Push the unit in the direction 1.
(2) Lift the unit in the direction of arrow 2 while performing step (1).
(1)
Let the hook on the Amplifier Unit's Fiber Unit
connection side catch the track.
(2)
Push the unit until the hook clicks into place.
